CONNECTNG-ROD.

Application 'filed March 6, 1920.

il'r Jamison, 4dites. residing at of Maricopa and invented nev.Y and Connecting-Rods, is a specification.

i o improvements in designed tor use or other machines, other capacities, such ne crank shaft and piston "ention is the provision in which the Wrist pin atieallj: adjusted to taire i. le a proper Working ii 1between the and rod.

Another obl'e is the provision oiC a connecting rod which also adjustable longitadinallj,v to increase or decrease the length ot the rod.

Si further object is the provision ot means for lubricating' the crank shaft connection or bearing1 which located at one end of the rod.

lilith the above and other objects in view7 the invention further includes the following novel features and details of constmicticn7 to he hereinafter more ifullj; described. illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

tion with a wrist pin il or similar member, a hearing which is adapted Ytor connection with a crank shaft 13 and a rod let, which connects the bearings l and l2.

The bearing l() comi/rises a casing` l which is provided u'ith an internally thread` ed extension lil, by means oi? which it may be connected to one end ot the rod vlli, being eld in adjusted position by means of the ofi-lied nutl l?. rlhe casing l5 is provided 'ith a transversely arranged elongated slot i8, which is preferably.' open at one side as indicated at l), the ivrist pin ll. being positioned at and ha Ying a bearing in one end of this slot. Located Within the slot 18 is a. movable bearing Wedge 20, one side oi this Wedge being conca-.ved so as to complete the bearing AIfor the pin ll.. While its opposite side edge is tapered as shown at 2l. ln. order to hold the bearing edge 2() against lateral movement with respect to the connecting rod proper, this Wedge is provided at each end with a lug Q2. which is adapted to slide in and engage the ivails oi notches 23 located at each end oi the casing l5. Also located within the slot i8 is a tapered pin 2&1-, which acts to force the wedge 2O into proper Working engagement with the ivrist pin ll, the engagement being controlled by a spring Q5, 'which surrounds one end of the pin 24 and has one end bearing against the casing l5. The opposite end of the spring 25 bears against a. Washer 26, the tension of the spring being adjusted by means of a nut 27. B v this means Wear in the bearing Will be automaticallj.'v taken up.

The bearing 12 comprises a block 2S Which carries at one end a bushing 29, for Contact ivith the crank of the shaft 13, a similar bushing being positioned upon the opposite side of the crank and being held in position within a stop 30. The stops are provided with apertured eas 3l through which pass bolts 32, the said bolts also passing through ape-rtured ears 33 formed upon an internally threaded connecting member or coupling 34. rlhis coupling is threaded upon the rod 14 and is held in position bv means ot a lock nut 35, While the end of the coupling member bears against the eno ot the block 2S.

The block 28 is provided with an oil chainber or reservoir 3G. within which extends a distributing pi ie 25T. 'the latter being provided ivith branches 3S to distribute the lubricant to each side oi the hearing.

It Will be seen from the foregoing descriL tion and the accompanying drawings, that the bearing l0 is constructed so as to automatically take up Wear, and that the length of the connecting rod may be adjusted by loosening the lock nuts 17 and 35 and rotating the rodlll, the threads at the oppositeends of which are oppositely inclined.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to malte such changes as properly fall Within the scope of the appended claims.

Having described the invention what is claimed is l. A self adjusting bearing comprising a casing having a slot in one face which eX- tends the entire length oi. said casing to provide a shaft engaging seatL a take-up block engageable with the shaft and movable transversely of the casing, laterally eX- tending lugs located at each end of the block and engageable with notches formed in the casing at each end of the slot to prevent longitudinal movement of the block and means for adjustably holding the block against transverse movement.

`2. A self adjusting bearing comprising a casing having a slot in one face which eX- tends the entire length of said casing to provide a shaft engaging seat, a take-up block engageable with the sha-ft and movable transversely of the casing, a longitudinally movable Wedge located Within the casing and engaging the block to hold the latter in position, a pin extending from one end of the Wedge, a spring surrounding the pin and engaging the block and casing to urge the take-up block in a direction toward the shaft and means for adjusting the tension of the spring.

In testimony whereofv I aiiiX my signature.
